Tunnel-coupled optical microtraps for ultracold atoms
Shangguo Zhu, Yun Long, Wei Gou +2
Arrays of individual atoms trapped in optical microtraps with micrometer-scale sizes have emerged as a fundamental, versatile, and powerful platform for quantum sciences and techno…
Periodic driving induced helical Floquet channels with ultracold atoms in momentum space
Teng Xiao, Dizhou Xie, Wei Gou +4
Employing the external degrees of freedom of atoms as synthetic dimensions renders easy and new accesses to quantum engineering and quantum simulation. As a recent development, ult…
Quantum Zeno effects across a parity-time symmetry breaking transition in atomic momentum space
Tao Chen, Wei Gou, Dizhou Xie +4
We experimentally study quantum Zeno effects in a parity-time (PT) symmetric cold atom gas periodically coupled to a reservoir. Based on the state-of-the-art control of inter-site…
Tunable non-reciprocal quantum transport through a dissipative Aharonov-Bohm ring in ultracold atoms
Wei Gou, Tao Chen, Dizhou Xie +5
We report the experimental observation of tunable, non-reciprocal quantum transport of a Bose-Einstein condensate in a momentum lattice. By implementing a dissipative Aharonov-Bohm…
Topological characterizations of an extended Su-Schrieffer-Heeger model
Dizhou Xie, Wei Gou, Teng Xiao +2
The Su-Schrieffer-Heeger (SSH) model perhaps is the easiest and the most basic model for topological excitations. Many variations and extensions of the SSH model have been proposed…
Topological quantum walks in momentum space with a Bose-Einstein condensate
Dizhou Xie, Tian-Shu Deng, Teng Xiao +4
We report the experimental implementation of discrete-time topological quantum walks of a Bose-Einstein condensate in momentum space. Introducing stroboscopic driving sequences to…
